The M10477 and M10478 incorporate the SiRFstarIV GSD4E 9333 GPS IC and all front end components with Antenova’s high performing GPS antenna technology in convenient, easy to integrate single package modules. Both modules operate on a single 1.8 V positive supply with low power consumption and several low power modes for further power savings. They are supported by SiRF stand-alone software and are compatible with UART, SPI and I2C host processor interfaces. The M10477 and M10478 also benefit from the company’s novel external matching which offers ease of tuning for each device platform.
